Severe Storms/Heavy Rain on August 12-13, 2012
 
A boundary (warm front) lifted to the north across Arkansas during the evening of 08/12/2012. The cold front that pushed through Arkansas on the 10th returned as a warm front on the 12th. During the evening, warm and moisture penetrated into the region from the southwest.

At the same time, a new cold front approached from the Plains, and triggered thunderstorms in eastern Oklahoma and northwest Arkansas. One storm near Tontitown (Washington County) produced tennis ball size hail. The satellite showed a cluster of showers and thunderstorms tracking along and north of a warm front in the Arkansas River Valley during the early morning hours of 08/13/2012.

Storms became more organized as they moved to the southeast along the warm front. They had plenty of energy available, with temperatures to the southwest of the front still in the 80s as of 100 am CDT on the 13th. Dewpoints were in the upper 60s/lower 70s (plentiful moisture).

 

Twenty four hour rainfall through 700 am CDT on 08/13/2012. The storms brought much needed rain, especially to central sections of the state. Twenty four hour amounts through 700 am CDT on the 13th included 3.65 inches at Mayflower (Faulkner County), 2.50 to 3.00 inches at Gibson and Sherwood (both in Pulaski County), 2.70 inches at South Bend (Lonoke County), 2.35 inches at Conway (Faulkner County), 2.15 inches at Lonoke (Lonoke County) and 1.81 inches at Stuttgart (Arkansas County).

There was some wind damage reported. Trees were blown down at Conway and Mayflower (both in Faulkner County). A few trees were pushed over at the Little Rock Air Force Base (Pulaski County), with a 55 mph gust measured. Lightning also triggered at least a dozen wildfires.

 

Later on the 13th, the new cold front swept through Arkansas, with additional isolated severe storms mainly in Arkansas and Desha counties (in the southeast). The satellite showed isolated severe storms in southeast Arkansas ahead of a cold front during the afternoon of 08/13/2012.

Farther to the west, much drier air (dewpoints in the 40s/50s) filtered into the state. Relative humidity levels dropped to less than 20 percent in some spots. This helped rekindle a wildfire just north of Casa (Perry County). It is believed the fire was started by lightning earlier in the day. The fire burned 700 to 800 acres and consumed at least one home and several barns. Close to the fire, 50 to 100 homes were evacuated. The fire was contained on the 14th.
